Positive Displacement PumpsPumping high temperature slurriesA key component in a High Pressure Acid Leach (HPAL) circuit is the Positive Displacement (PD) pump that must pump high temperature (200 Celsius plus) slurry, containing the Nickel rich ore, to the autoclave for acid leaching. In a ...
positive-displacement pumpsignal analysisdiagnostic of machinesThis study presents a possibility of detecting wear of a valve plate in multi-piston axial pump based on time-frequency analysis of measured signals. Short-time Fourier transform STFT and the generalized Wigner-Ville algorithm WVD were used...
Screw pumps can pump fluids of significantly higher viscosity than centrifugal pumps. Changes in pressure differential have little impact on the flow rate of positive-displacement pumps compared to centrifugal pumps when pumping viscous product. Disadvantages In comparison to other types of pumps, h...

registering a CAGR of 4.1% between 2016 and 2021. Variable displacement pump is a type of positive displacement pump, where the volume of the fluid pump can be changed while the pump is running. The primary function of the variable displacement pump is to convert the mechanical energy into hy...
nozzle capable of dispersing adhesive36supplied by the adhesive reservoir28at a particle size of 50-100 μm. Adhesive may be supplied under pressure by use of a pressurized gas as a propellant, a positive-displacement pump, or by other means known in the art....
Liquid ring vacuum pumps can be considered to be positive displacement devices with volumetric flow (at the suction) being proportional to shaft speed. As long as the pump is operated within its speed range capabilities, you should be able to reduce the flow rate fairly readily. The temperature...
